Specification of Letters Patent.

Application filed September 23, 1909. Serial No. 519,207.

Be it known that I, EDWARD N. PAonLsEN, a citizen of the United States, and a resi dent of'the city of Detroit, in the county of Wayne and State of Michigan, have invent-. ed anew and Improved Starting Device for Explosion-Engines, of which the following is a specification.

This invention relates to means for introucmg a charge of explosive mixture into the explosion chamber of internal-combustion engines, and the object of my improvements is to provide a device whereby the charge will be led to the proper cylinder and no other.

My invention consists in combination with a carbureter and hand pump, of pipes for conducting the explosive charge to the various cylinders, of a valve for selectin the pipe through which the charge shal pass actuated bye the pump, and an auto- My invention further consists in combination with this charging device, of means or opening and closing valves in said pipes and simultaneously opening and closing the electric igniting circuit.

In "the accompanying drawings, Figure 1 is a plan of an explosion engine with my improved starting device -in position. Figs. 2 and 3 are details of valves in the feed pipes. Figs. 4 and 5 are central vertical, cross sections ofthe selecting valve and the cam for controlling the same. Fig. 6 is a cross section on the line 6-6 of Fig. 7. Fig. 7 is a detail of the selecting valve. Fig. 8 is a cross section of the pump. Fig. 9 is across section of a carbureter. Fig. 10 is,.-a detail of a switch.

Similar reference characters refer to like parts throughout the several views.

To start a dead multi-cylinder, auto- H mobileengine an explosive charge mustbe introduced into the proper cylinder. By means of the construction shown and described, this can be done by the chauffeur without'leaving his seat. The construction comprises a carburetor and a hand pump of any desired type, a selecting valve controlled by the engine itself, "preferably through a cam on the cam shaft, and a selecting valve to The carburete'r shown in Fig. 9 has a may be employed and mounted body 1, a cover 2, and a Wire receptacle 3 withinthe body which holds a body' 4 of] loose cotton waste or other absorbent material. A wick 5 connects to this absorbent material and extends to a source of supply, preferably to the main fuel supply pipe 6, which connects to the main engine carbureter 7. (Fig. 1). A valve 8 in the bottom of the carburetor body 1 admits airto the same while a pipe 9 connects to the pump. Any other desired carbureter may be employed and mounted in any convenient place.

' The pump 10 shown in Fig. 8 has a cylinder 11, upper head 12, 'lower head 13,

p ston 14, piston rod 15 with knob 16 on the outer end, inlet valve 17 connecting to the carburetor by valve '18 by means the pipe 9, and outlet connecting to the selecting valve ofthepipe 19. Any other pump n any convenient position.

The selec'tin valve has a body 20, an up per head 21, a lower head 22, a hollow piston 24, a cored piston rod 23, and an extension -or finder 25 at the lower end of the piston rod. This selecting valve will be mounted adjacent to'a constantly moving part of the engine,' and. on four-cycle engines, preferably adjacent the camshaft which actuates the valves, as this shaft. usually revolves once for each complete operation of the engine. On this cam shaft 28 is secured a cam 29 having steps 31, 32, 33 and 34. Which step is adjacent the finder will depend upon the position of the movable parts of the en- Patentcd June '7, 1910.

gine, that is, will depend upon in which cylinder the next explosion is due. It is obvious that the cam should be so positioned on the cam-shaft that when the finder 25 engages it, the valve\24 will be so positioned that the explosive mixture will be forced into the proper cylinder. In a fourcylinder, four-cycle engine, the cam shaft makes one revolution for each four explosions, so that four steps on the cam 29 will properly position the valve 24 when the finder is forced down in contact with the cam during the operation of the charging mechanism.

Within the piston 24 is a perforated cross bar 35, in which and in a bore of the, piston rod 23 is mounted a stem- 36 having an inlet valve 37 at its upper end, normally held loo against its seat by the spring 38. The spring 39 normally holds the piston 24 up and holds the finder 25 away fromthe cam 29. The piston 24' has four outlet apertures 404142 and 43 whichregister respectively with the the cylinders 52-53-54 and 55 respectively.

selecting valve, wh1le stop-cocks 57 maybe 7 ing valve-through the pipe 19. As pressure until the valve 24 is positioned. Increased pressure in the pipe 19 will force the inlet "cylinders prevent the passage of burned forming a vplosion of the charge thus introduced starts ports 44-45-46 and 4:7 in the wall of the valve body. Pipes 4-8-4950 and 51 connect these ports to the explosion chambers of Check valves 56 in these pipes adjacent the gases irom the explosion chambers to the placed: inthes'e pipes for ample security' The plugs 58 of these stop-cocks havelev'ers 59 which all connect to the rod 60 extending throughthe dash-board 61, when used on an automobile, where the rod; has a knob 62. This rod may be employed to break the igniting circuit of the engine. The rod may be grounded on the engine. At some convenient place, preferably near the end 68 of the, rod, an insulated switch ,member 64: is mounted and connected to it is the wire 65 {portion of theigniting circuit. The end 0' the rod GO may be properly formed to close the circui as shown in Fig. 10. The operation of he device isas follows.

When it is desired to start a dead 1, engine, the operator pulls the knob 62 inward thereby turning the levers 59 to the posi. tions shown in- Fig. 2 and indicated in th' dotted lines 67in Fig. 1; thus opening all the stop-cocks 57 and opening the igniting circuit. It will be understood that this may be either they primary or secondary circuit when a double circuit system is employed. The operator next actuates the pump 10, drawing" air through the saturated fibers and forcing the resulting explosive mixture to the selectaccumulates within the body 20, the piston 24: is forced down until the finder 25 rests on the cam 29, ,thus properly positioning the valve 24. As the spring 38 is stiffer than the spring 39 the valve 37 will remain seated valve 37 from its seat when the explosivemixture will flow through the properlaperture in the valve 24 and port in the body 20, and through the selected pipe to the proper cylinder. After the cylinder has been prop' erly charged, the pump is sto ped. The

ressure above the valve 24 imme lately falls ecause of the very small vent 68 in the pipe 19, shown in Figs. 4 and 5. The valve 37 will promptly close and the valve 24 rise, lifting the finder 25 from the cam. Th rod 60 is then pushed forward, closing the sopcocks 57 and the igniting circuit. The exthe engine.

The location'of the pipes 48-49-40 and 51 will depend upon the circumstances. Their diameter may be quite small, and one inch is usually a sufficient diameter for the selecting-valve iston 241. The details 0 construction and mounting ee eec of this device may bevaried by those skilled in the art without departing from the spirit of my invention.

Having now described my construction,
